"Canon is also introducing a new EF-S 18-135mm f/3.5-5.6 IS USM lens optimized for high-speed autofocusing when shooting stills and quiet and smooth zoom when shooting video. The lens is also compatible with Canon’s new Power Zoom Adapter for smooth cinematic ‘pulls’ when changing focal length on a subject, and responsive adjustments at the push of a button for stills or video."

Indeed, those new items are all compatible with the 70D. The headphone jack is my primary motivator for putting my 70D up for sale and transitioning to the 80D... since I can't justify what I really want, and that is the 1DX Mk. II.

I might be right in line behind you. The one feature I'd also like to see with the 80D not mentioned anywhere, is whether wi-fi is disabled in movie mode. That's my major pet peeve with the 70D.

Agree with you 100% total lack of luster and innovation, Canon continues to sleep in this rapidly changing field, this camera is stale in specs from the beginning, and no 4K video capabilities make it a liability from day one.
sleep well Canon, no one will bother you.

As for the lens adapter would have been nice to have it for all canon lenses rather than just for the plastic kit lens.

The power zoom adapter has an electronic connection interface to enable communication with the lens. You can see this in the third photo of the press release which is linked at the top of this post.

The new EF-S 18-135mm "Nano USM" is the first lens to accommodate this new connection; previous lenses do not have it so therefore they are not compatible. Hopefully we'll see more new lenses that are.
